cyanobacteria

In yesterday’s Greenwire (subscription required), reporter Paul Voosen reviews of the efforts of various firms to develop commercially competitive motor fuel from two types of single-celled photosynthetic bugs — algae and cyanobacteria.

For several years, biofuel entrepreneurs and alt-energy gurus touted oil extracted from algae as the next big thing — abundant, cheap, home grown, hi-tech, carbon neutral. In addition, unlike corn-ethanol production, growing algae in ponds or bioreactors would not inflate grain prices or divert food from hungry mouths into gasoline tanks.
